Main Product Features

  1. Calibrated gPV characteristic reliably trips low-magnitude leakage and ground faults inherent to PV wiring systems
  2. 1000VDC voltage rating matches mainstream residential and commercial solar string voltage frameworks
  3. Stable performance under variable sunlight ripple load, prevents unnecessary premature fuse blow
  4. Robust ceramic construction withstands harsh outdoor day-night temperature cycling year-round
  5. Tin-plated copper end caps minimize contact resistance and heat buildup during long continuous runtime
  6. Standard HP10M outline fits all matched PV fuse holders, spring clips and combiner box mounting bases
  7. High 50kA DC breaking capacity rapidly isolates catastrophic short-circuit faults in PV branch loops
  8. Direct OEM replacement for grid-connected and off-grid solar combiner box string protection circuits

Wide Application Range

Residential rooftop solar panel string overcurrent safeguard
Commercial PV combiner box DC branch circuit fault protection
Off-grid solar charge controller input circuit safety control
Small solar power station medium-current string wiring loops
Solar tracking unit DC feed cable overload protection
